For example:
A system error has occurred, and you have noted that the BladeCenter T
system-error LED is lit on the system LED panel. You then locate the module or
blade server that also has an error LED lit (see “BladeCenter T unit power, controls,
and indicators” on page 19 for the location of error LEDs; see the documentation
that comes with your blade server for the location of error LEDs on the blade). If the
component is a module, replace the module. If the component is a blade server
with its system-error LED lit, follow the instructions in the documentation that comes
with the blade server to isolate and correct the problem.
